Q1.Choose the word from the options given below that is most nearly opposite in meaning to the given word:
Frequency
Answer : Option BExplaination / Solution:
Periodicity is almost similar to frequency. Gradualness means something happening with time. Persistency is endurance. Rarity is opposite to frequency
Q2.The horse has played a little known but very important role in the field of medicine. Horses were injected with toxins of diseases until their blood built up immunities. Then a serum was made from their blood. Serums to fight with diphtheria and tetanus were developed this way.
It can be inferred from the passage that horses were
Answer : Option BExplaination / Solution:
Option B fits the sentence, as they built up immunities which helped humans create serums from their blood.
Q3.The question below consists of a pair of related words followed by four pairs of words. Select the pair that best expresses the relation in the original pair:
Gladiator : Arena
Answer : Option AExplaination / Solution:
A gladiator performs in an arena. Commutators use trains. Lawyers performs, but do not entertain like a gladiator. Similarly, teachers educate. Only dancers performs on a stage.
Q4.Choose the most appropriate word from the options given below to complete the following sentence:
It was her view that the country’s problems had been_________ by foreign technocrats, so that to invite them to come back would be counter-productive.
Answer : Option CExplaination / Solution:
The sentence implies that technocrats are counterproductive (negative). Only (C) can bring the same meaning.
Q5.Choose the most appropriate word from the options given below to complete the following sentence:
Under ethical guidelines recently adopted by the Indian Medical Association, human genes are to be manipulated only to correct diseases for which______________ treatments are unsatisfactory.
Answer : Option DExplaination / Solution:
Available is appropriate because manipulation of genes will be done when other treatments are not useful.
Q6.Consider the following statements regarding the complex Poynting vector for
the power radiated by a point source in an infinite homogeneous and lossless
medium. Re() denotes the real part of denotes a spherical surface whose
centre is at the point source, and denotes the unit surface normal on S.
Which of the following statements is TRUE?
Answer : Option CExplaination / Solution:
Power radiated from any source is constant.
